Portfolio overview

Toshiba Kikai Kabushiki Kaisha has been granted 109 US utility patents between 2015 and 2022, placing Toshiba Kikai Kabushiki Kaisha at rank #3,417 across all assignees tracked by PlainPatent. This portfolio spans 50 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.1 claims per patent with primary concentration in B29C (SHAPING OR JOINING OF PLASTICS; SHAPING OF MATERIAL IN A PLASTIC STATE, NOT OTHERWISE PROVIDED FOR; AFTER-TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING). As a Foreign Corporation, Toshiba Kikai Kabushiki Kaisha is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Toshiba sits between Storedot, Ltd. (109 patents, rank #3,413) and Berry Global, Inc. (108 patents, rank #3,421) - the closest US assignees by grant volume. The composite Innovation Score of 46.4/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Between 2020 and 2025 the company received 24 grants, compared with 85 in the 2015–2019 window, a -72% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Toshiba Kikai Kabushiki Kaisha's 8.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 50 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Toshiba Kikai Kabushiki Kaisha against peers pursuing similar technology classes.
